No. 46. 
ERAGROSTIS CURTIPEDICELLATA Buckley. 
Plant perennial, tufted with numerous oma culms at bulbous base. 
Roots coarse, with dense, tawny root hair 
Culms stout, erect, ee branching, ere nearly solid, smooth, 1 to 2 
feet tall. 
Leaves of sterile wales rather numerous, with more or less involute blades 3 
to 6 inches long; of stem 4 to 8; sheaths exceeding the internodes, open and rather 
loose above, smooth or with few scattered hairs along the exposed margins; blade 
involute toward the tapering point, 2 to 2} lines wide, 4 to 6 inches long, smooth, 
rigid; ligule and throat, a row of fine hairs 2 to 24 lines long; sheaths and lower 
sides of leaf often glandular viscid. 
Inflorescence an oblong pyramidal erect panicle 8 to 12 inches long; spreading 
branches 3 to 5 inches long, much subdivided, mostly alternate, with tufts of 
white hairs in the axils, the solitary cg pete spikelets borne mostly on strict, 
hispid lateral branchlets. 
Spikelets, oblong-linear, less than 1 line wide, 2 to 3 lines long, often purplish, 
on hispid pedicels less than half their own length, internodes of the slightly zigzag 
rachilla 4 line long; first and second glumes ovate, acute, carinate, thin, herba- 
ceous, l-nerved, minutely hispid on keel above, 4 line long; floral glumes lanceo- 
late, acute, prominently nerved, ? line long; palet linear, curved so that its two 
pubescent nerves appear outside of the flowering glume. 
Grain, amber color, narrowly cylindrical, + line long. 
PLATE XLVI; a, spikelet; b, empty glumes; ¢, floral glume; d, palet. The 
figure does not show the hairy ligule. 
This species is closely related to E. pectinacea, being less diffuse, with shorter 
branches and larger spikelets. 
It seems to be pretty closely confined to Texas and northward to southern 
sas. ;
